Chassis Batteries New, as are House Batteries. (Both within 6 months). Drove last 1 Aug. I have started both coach and generator every other week since with no issues. Yesterday, no lights, fan, water pump or slides. On shore power, 50 Amp. Thoughts?

The go-to answer for this question given that all the items you have listed are 12V, is to check the Battery Cutoff Switch. Usually in the stairwell.

It’s common for the switch to get bumped, and it’s also common for the solenoids which are controlled by the switch to go bad. We replaced ours last year.

If the switch is on, then check for 12V power at the solenoids. The solenoids can be bypassed or “jumped” if needed to get you going, just bolt the main wires to the same post on the solenoid. Assuming you feel comfortable working with electrical power items, if not then a shop can help you out. I’m on a mobile browser at the moment so can’t tell if your coach model is in your signature, but if you confirm the model then it will be easier to advise on which solenoid is required, if replacement is needed.

Hope that gets you started.

All the best!

Breaker at shore power pedestal

X2 on the salesman switch and or solenoid.

Only other thing to check if it is your 12 volt distribution system there may be a circuit breaker protecting the fuse panel. You may have to pull out a volt meter and check the circuits starting at the battery cut off switch.

Im hooked up to 120v at my house. I have 120v inside the coach. Just no 12v, eg, slides, lights, panel display, water pump.

Jim, thats my next step. I know the batteries are good. BTW, I had good power until about a week ago.

Does your inverter display show voltage of the batteries? What state of charge is the inverter in for the batteries?

I'm sure your 12 volt power distribution is different then mine so hard for me to tell you where to look and what to look for.

My 12 volt house power is controlled by a white roger solenoid that is controlled by a switch at the front door. If the switch is in the off position there is no power to lights, water pump etc.

But all of my 12 volt power can be isolated via the battery disconnect. If you have power to the inverter that tells me the disconnect is probably good as the only other thing that could be wrong would be a large fuse protecting the inverter and this seldom fails.

Jim, the Inverter green light is on. When I turned off the salesman switch and then turn back on, nothing happens. (Had to do that when I replaced the house batteries.

When I turn off the Big Boy switch for chassis and house and then back on, I’m in the same state of having 120v, but no 12v. I’m really stumped. Thanks for your insights though.
